Ya, I've done a few Megabus trips from Dallas Metroplex to AUS for some cheap fares; of course that is over five years ago.
And having flown out of IAH for 15 years I am all too familiar with the hub penalty - or as (IIRC Larry Kelner or his successor at one of the Continental Airlines
DOs at IAH) called it, nonstop premium.
So I did AUS-IAH-BOG and DAL-IAH-MNG on CO and somehow managed to forget to get on board of connecting flight after clearing customs / immigration at IAH

WN to "originating" airports.
